FEED DEVICE FOR ROLLING-MILLS.

Specification of Letters Patent.

Patented Illa-r, 4c,

Application filed September 5, 1912. Serial No. 713,685.

To all whom, it may concern Be it known that l, HOWARD ll. Coon, a

citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented a new and useful Feed Device for Rollin -Mills, of which the following is a specification.

My invention relates to apparatus used. in handling and conveying metal between the successive passes of the rolling mills in which the material being rolled is elongated and reduced in thickness, and the invention more parti ularly relates to the apparatus used in handling and conveying the i'naterial in manufacturing long and relatively thin metal strips such as pipe skelp. In rolling such materials with the apparatus used heretofore it is frequently necessary for-an operative to use a bar to lift or pry the forward or entering end of the material being rolled into a position in which the end of the material will enter the bite of thc reducing rolls, this being eti ected by an expenditure of labor and at thecost of an expensive interruption or delay in the rolling opera time.

One object of my invention is to provide apparatus for handling such materials having novel means whereby the advancingior forward end of the material being rolled is moved in such manner as will automatically bring it into position to enter between the reducing rolls without the necessity of manual assistance or interruptions and delays in the rolling operations.

Referring to the accompanying drawings forming part of this specification, Figure 1 is a sectional elevation showing a stand of reducing rolls and a delivery table by which the materials are handled and conducted to the rolls constructed and arranged in accordance with my invention. Figs. :2, 3 and lare detail sectional end elevations, on a larger scale, showing modifications in the construction of the agitator forming part of this invention Fig. 5 is a plan partly in section of the ,pparatus shown in'Fig. 1.

In the drawings 2 designates the roll housings of the usual construction having a twohigh stand of reducing rolls 3 and 4 mount-- ed in the windows thereof in the usual manner. The rolls 3 and 4, which form one of stands of rolls in a continuous mill, ro-

at all times in the direction indicated Jae arrows and a feed table 5 is provided in the rear thereof on. which the materials being rolled are moved lengthwise to the entering side of the reducing rolls and l.

The feed table may be of the old and well known construction in which a series of feed rollers 61love shafts 7 on the opposite ends or which the rollers are mounted in bearings 8 carried on the side frames 9 oi the feed table. One end of each of the shat'ts T is provided with a bevel driving gear 12 which meshes with a. bevel driving gear 13 on a line shaft 14rextending lcngtlr wise alongside one side of the roller table, the line shaft being driven through slowdown gears by a suitable motor in the usual and well known manner. The motor and slow down gears being old and well known, and not forming part of this invention, are not shown' The feed rollers 6 may be grooved or provided with annular flanges to assist in maintaining the materials being rolled in aline ment with the several passes in the reducing rolls when the rolls are provided with a se ries of g o ved passes or may have plain, cylindrical faces as shown.

The end roller 6 of the feed table or the feed roller nearest to the reducing rolls 3 and i, is provided with a series of ribs 10 which extend lengthwise parallel with the axis of the feed rollers as shown in Fig. 1.

Instead of having the series of tour ribs 10 as shown in Fig. 1, a plurality of project* ing'knobs or pins ll may be employed, as shown in Fig. 2, or a roller which is rectangularas shownin 3, or polygonal in cross section as shown in Fig. i, may he can ployed to effect the some result.

In the operation oi 11'! improved appa' ratus the nui-terials are uced between. the rolls 3 and 4 in the usual manner and are caused to travel lengthwise to the rolls on the rollers (3 of the feed table as heretofore. When the forward end of the thin, heated and very flexible blank A being rolled passes the end roller 6 in traveling lengthwise to the rolls 8 and 4 its outer end will sag downwardly or in some cases be bent upwardly so that it oft-times becomes necessary to lift or lower the forward end of the metal blank A into position to enter the bite of the rolls. With my improved apparatus, as the feed rollers 6 are rotated to deliver materials lengthwise, the forward end of each blank A. after passing the corrugated or ribbed end roller 6 on the roller feed table, will be alternately raised and lowered by this teed roller so that the extreme end of .the material will be caused to move ver- 5 tically across the bite of .the reducing rolls 3, 4. As the other feed rollers 6 in the feed table are-constantly acting to feed the material forwardly, such action together with the raising and lowering movement of the 10 end feed roller (3 will niechanically introduce the end of the material being rolled into the bite of the rolls 3, 4 and in this way prevent interruption in the forward movement of the matei ials on the roller feed table, and avoid the necessity of delays in the rolling operation otherwise necessary to permit of the movement manually of the end of the material into position to enter between the rolls.

The advantages of my invention will be apparent to those skilled in the art. The apparatus is simple and is easily keptin repair. By its use delays heretofore caused in effecting the entrance of the material between the reducing rolls are prevented and overcome and a continuous rolling op eration is thereby assured. 4

My improved apparatus, while primarily r intended for use on small mills in which the smaller sizes of skelp are rolled, is equally applicable to mills rolling the larger sizes of skelp, t0 pl, mills, and to all mills rolling long, thin nezrible materials.

Modifications in the construction and arrangement of the parts may be made without departing from my invention. The number of longitudinal ribs on the agitator roller on the end of the feed table and its location in the length of the feed table may be changed. The cross sectional contour of the agitator roller may be modified invarious ways, and other changes may be made within the scope of the appended claims.

lVhile the invention is particularly a'dapted for use on rolling mills, it may be employed wherever it is desired to feed materials into the grasp of rotating members, such as rolls of various kinds,- cutting or abrading cylinders, and the like.

I claim. f 1. In a T c-lling mill the combination with the redncm g rolls and a roller feed table for deliweringmaterial to said rolls, of a roller on said feed table having means whereby the end of the materials carried thereon is moved vertically in presenting said materials to the bite of said reducing rolls.

In a rolling mill the combination With the reducing rolls and a roller feed table for delivering material to said rolls, of a roller on said feed table having projections on the surface thereof whereby the end of the materials carried thereon ismoved vertically in presenting said materials to the bite of said reducing rolls.

3. In a rolling mill the combination with the reducing rolls and a roller feed table for'delivering material to said rolls, of a roller on said feed table having longitudinal ribs at intervals on the surface thereof whereby the end of the materials carried thereon is moved vertically in presenting said materials to the bite of said reducing rolls.

In testimonywhercof, I have hereunto set my hand.
